Group Companies amongst the best of Brazil

The priority given to investments in quality in the last three years has enabled important gains in the quality indicators of Energisa Group‘s distribution companies.

All of the Group’s distribution companies saw their FEC diminish in 2017 remaining below the regulatory limits. The best DEC performances were reported by the distribution companies in the south-east and north-east, whose results fall below the regulatory limit. 

The climate in the concession areas of the distribution companies in the Midwest and North was highly challenging in 2017 compared with 2016. According to the National Institute of Spatial Research – INPE, in Mato Grosso do Sul state, the rate of lightning strikes was 65% higher in 2017 than in 2016. Despite this, EMS still closed the year within the regulatory target.

In Mato Grosso, lightning strikes in 2017 were 42% higher than in 2016. Higher than average, strong winds and heavy rainfall also impaired further DEC improvements at EMT, especially in the months of October and November.  However, additional measures in progress since mid-2017 saw the metric improve in the last month of the year.

The state of Tocantins experienced a similar climatic situation, seeing lightning strikes rise by 173% in 2017. Most of the strikes occurred in November and December, months when rates were 263% and 277% higher than in 2016, respectively. However, the delivery of the quality recovery plan at ETO, which involved increasing the number of teams and investing in grids, was a resounding success, leading to a reduction of 4.26 hours in the concession’s DEC in the year and pushing the company close to the regulatory limit (under 1 hour).         

Also note that in 2015 the companies EMG, ENF and ESS renewed their concession agreements, meeting the minimum quality standards required in the new agreement for the second consecutive year.

The quality indicators performed as followed in 2017:

Distribution companies DEC (hours) FEC (times) DEC limit FEC limit
